Thanks, I was really excited to find one in that kind of shape, just a couple dents in the tanks smaller than a dime and the gas cap is pushed in a little. Thanks for the link. There were also a couple other rubber parts that are pretty degraded, specifically a piece that connects the upper and lower pieces of the water inlet up to the powerhead, and another piece that seems to be between the water outlet from the jug and the exhaust manifold. Do you know if those are reproduced too or if there’s a fix that other people have done? Also, do you know if parts from a similar model will fit? I have the finned jug but I see the ones with the smooth jug (I assume later models?) on ebay like the 571.40, would any of those parts be interchangeable? I’ll have to dig into this thing soon but first I have a mini bike with a Clinton Panther to fix.

Ok, I’ll probably be posting an ad as soon as I tear into it and check what exactly I need. If I can’t find a new rod I’m sure there’s someone in my general area that would be able to get it back in order. I’m just hoping the cylinder isn’t scored because I would assume a rod knock like that would only develop if it was run low on oil

Would you happen to have any spare parts from the other engines in case I need something else? And if my water pump is worn out is there a fix for it?

Ok, that’s giving me more confidence. I don’t think the gears are ruined because there’s very little slop when I turn the motor over. I wonder why since the motor is so nice that it has such a bad rod knock? I’ve had much worse motors that were completely fine. I think I’m going to tear into it this week. Just figured out the carb issue on my mini bike so this is my next project
